LIQUD-FUEL BURNER.

Application filed May 2, 1921. Serial No. 466,141.

To all whom t may concern:

Be it known that JORDAN lVnciuAN, a citizen of the United States;A and residing at Greve Couer, St. Louis'County7 Missouri, have invented the new and useful Improvement in Liquid-Fuel Burners, of which the followingis a specilication.

This invention relates to oil burners and more particularly to that type of oil burner in which a wick is employed to feed the fuel to the iame such as is used in oil stoves.

The ordinary oil burner of this type usually has an oil reservoir into which the wick is adapted to dip and which is fed by a supply pipe from the main oil tank. It is desirable in this type of burnerA to have the oil reservoir into which the wick dips as small as possible so as to avoid storing a large quantity of fuel in the burnen since such fuel is liable to cause a great fire risk.

The oil reservoir on this type of burner is usually constructed to have small capacity, and since a cylindrical wick is used, this means that the reservoir usually takes the-form of a double-walled cylindrical container with just enough space between the inner and outer walls to accommodate the movement of the wick and to form a small reservoir for fuel.` In this type of construction1 the oil reservoir is not accessible on the inside for cleaning. [is it often happens that burners of this type are allowedto become clogged with dirt or with materials spilled during cooking operations, which are liable upon cooling to become hardv` it is very important to have such burners easily accessible on the inside and outside for thorough cleaning.

One of the obj ects of this iiwention.y therefore7 is to provide a burner of this type which shall be capable of kdisa-ssemblyr in such a way as to render it easily accessible inside and outside for cleaning.

Another object of this invention is to provide such a burner having a'fuel reser-l voir of limited capacity which at the same time may be constructed and arranged so that upon dissasembly, ample room is provided for easy access into the interior thereof,

.Further objects will appear from the detail description taken in connection with the accompanying drawing, in which:

Figure l is a cross-sectional view of a burner embodying this invention; and

Figure 2 is a partial sectional view showing another lembodiment of this invention.

Referring to t-he accompanying drawing, the burner comprises a chimney 1 within which are arranged perforated cylindrical tubes Q and 3- adapted to provide a space therebetween for the flame to travel, the perforations providing access for air to the flame from within and without. In the interior of the tube 3 is arranged a distributor 4 in which the air rising through the draft tube is dispersed to the sides of the tube 'The tubes 2 and 3 and the chimney 1 are supported by a spider 5 mounted on a vertical rod 6 by means of which they may be raised and lowered. rlhesc parts may all be of any well known construction.

The tube Q rests upon a flange 7 .on the wick tube 8. This tube is of special construction and is provided with an `outer cylindrical wall 9 and an inner eylindrical wall l0. These may be formed'ofone piece of metal or they may be joined at the bottom by a plate ll making tight joints So as to provide a fuel reservoir in the annular space between the walls 9 and l0. The walls fl and l0 are spaced from one another and the wall l() terminates at a lower level than the wall 9 so that ample space may be left between the upper edges of the two walls, for access to the interior of the reservoir.

In order to reduce the fuel capacity of the reservoir, a filler l2 is provided to 0c* cupy a major part of the interior space thereof. This filler is constructed with an exterior cylindrical wall 13 and an interior wall 141 joined by a bottom plate l5, which construction may be similarto that of the wick tube 8. The 4filler maybe closed at the top by a hori'lzontalv plate 16. should be tight soasto prevent leakage of fuel into the interior of the filler. 'The eX'- terior wall 13 of the filler may be provided with a smooth unbroken surface over which the wick 17 is adapted to move for adjustment of the flame. The wick may be All joints provided With the usual perforated tube 18 attached thereto and adapted to engage the adjusting wheel 19 whereby it may be raised or lowered for adjusting the flame. An attachment 2f) is provided for connecting the reservoir with the fuel supply. The interior wall 10 of the Wick tube ma be provided at its upper edge with threat s 21 or any other suitable attaching means and the interior wall 14k of the filler may be provided with similar attaching means lapted to engage the means 21 so that the filler when inserted into the reservoir may be securely attached to the Wick tube. The Wall 1lA may be provided with a spider 22 attached thereto and carrying a guide-tube 23 through which the rod 6 may move up and down for raising and lowering the chimney 1. The rod 6 is also usually provided with an offset 24 adapted when the rod is rotated to engage a rest 25 so as to hold the chimney in a raised position.

1n the embodiment shoivn in Figure 2 the vvick tube 8 has its interior Wall l() arranged inside of the Wick 1"? which is adapted to move thereover during adjustment. In this `case the exterior Wall 9 terminates at a lower level than the interior Wall so as to provide a Wide mouth for the reservoir to insure easy accessibility. The filler l2 in this case is arranged outside of the wick and carries on its interior Wall lll the Wick adjusting device 19. In this case the securing means 21 are provided at the upper edge of the exterior Wall 9 of the reservoir and are engaged by similar securing means mounted on the `exterior of the filler as shown in Figure 2.

The spider 22 carrying the guide-tube 23 is mounted on the interior wall 10 of the reservoir.

It Will be seen that this invention acconr plishes its objects. A Wick tube is provided which is adapted to form a, fuel reservoir having its interior and exterior walls spaced from one another so as to provide accessibility and the excess fuel capacity so provided is then eliminated by introducing a ller. The interior Wall of the Wick tube provides an unobstructed draft tube to supply an ample quantity of air to the lllame. If the burners should become clogged, it is only necessary to remove the iller after which all interior parts are easily accessible and all foreign matter may easily be cleaned out.

It is obvious that various changes may be made in details of construction Without de- 'parting from the spirit of this invention;

it is, therefore, to be understood that this invention is not to be limited to the specific details shown and described.
